I have the solidworks stl file of my robot, but how can I convert it into urdf file? I have tried simmechanics_to_urdf, but it seems don't work at all. For example, the stl file is test.stl (asscii), which pkg and node can do this job. Thank you.

2012-06-03 22:15:41 -0500 asked a question how can I build probability maps with gmapping

I want build probability maps, but I find that gmapping can only generate maps with 3 values (unknown, free and obstacle). How can gmapping work with probablility maps. Thank you. Further, I change source code, but it doesn't work too.

the code I changed is below: if(occ < 0) map_.map.data[MAP_IDX(map_.map.info.width, x, y)] = -1; else map_.map.data[MAP_IDX(map_.map.info.width, x, y)] = (int)round(occ*100.0);
